Triple Point of Water Cells

Product catalog summary

Overview: The document discusses the 5901 Series Triple Point of Water (TPW) Cells by Fluke Corporation, Hart Scientific Division. These cells are crucial for temperature calibration, providing a reliable standard with high accuracy and low cost.

Key Functions of TPW Cells:

Thermometer Drift Detection: TPW cells help identify unacceptable thermometer drift between calibrations.
Calibration Point: They offer a critical calibration point with minimal uncertainties.
Probe Characterization: TPW cells allow for easy updates to thermometer characterizations, extending calibration intervals.
Temperature Scale Intersection: The TPW is where the ITS-90 and thermodynamic temperature scales meet, with a defined value of 273.16 K (0.01 °C).

Construction and Composition:

Materials: Made from glass or quartz, containing pure water and vapor.
Isotopic Composition: Uses water with isotopic composition similar to Vienna Standard Mean Ocean Water (VSMOW) to minimize errors.
Impurities: Multiple distillation processes ensure water purity, reducing potential errors.

Product Variants:

Available in four sizes with different immersion depths and shell materials (glass or quartz).
Models include 5901A, 5901B, 5901C, and 5901D, each with specific features and dimensions.

Accessories and Options:

Quick Stick Immersion Freezer: Facilitates rapid ice mantle formation.
Insurance: Available for accidental damage coverage.
Isotopic Composition Verification: Options for testing isotopic composition of water cells.

Specifications:

Expanded uncertainty is less than ±0.0001 °C, with reproducibility within 0.00002 °C.
Different models have varying dimensions and immersion depths.

Catalog excerpts

The ITS-90 recommends thatwater cells be made from water with substantially the isotopic composi-tion of ocean water.Ӕ Research hasshown that TPW errors associated with isotopic composition can be as large as 0.00025 C. The uncertaintycontribution from VSMOW errors inHart cells is less than б 0.000007 C. ThatВs seven micro-Kelvin!Hart offers two options for verify-ing the isotopic composition of any purchased water cell, both at nomi-nal costs. We can submit to a testinglaboratory a sample of water taken from your own cell ( after it was com-pletely manufactured, so you get avalid comparison)...
